Description
Technical field
The present invention relates to a kind of dismountable lead extension, described lead extension is used for using in the seabed with the fixing lead part in seabed, these described parts are formed lead jointly, described lead is used for assisting obtaining described parts in the absorbed landing (focused landing) of pre-position in the process that parts is dropped to submarine structure from the underwater, and described lead comprises that partly upwards (in the position of using) that be designed to bottom (in the position of the using) engaged at end of described lead extension stretch out the end.
Background technology
With undersea device on the seabed structure or structure (such as, manifold or well head) when falling, often use guidance route (guideline), be generally cable wire.Each guidance route ends at the structure that is fixed on the seabed and from the lead that this structure is stretched out.Guidance route is used in the process of oil probing or production operation positioning parts on seabed base portion or ground (foundation), or in order to module is installed on the top of each other.In the probing of submarine well, for example, the template direction ground is laid around the conductor casing of the well of being drilled.The guiding ground has lead, and these leads are used to preventer BOP is positioned at the top of well head.Lead can also be used to install and locate other modules, for example, and with lower standing tube assembly guiding and be positioned on the preventer, or on the urgent separation assembly on the well workover safety valve.
Such lead provides the coarse alignment between equipment and the well head, and vertical steadiness is provided in system, in order to can form the connection to well head.Carry out final alignment by connector self.Usually, will in the process of step-down operation, use four leading lines and four posts.
Use a problem of the traditional direction post of this character to be: they are very long, and in water than equipment itself upwards more the highland stretch out, therefore suffered the infringement from fish trawlnet or similar item more.
Therefore, developed and introduced the lead extension in recent years, this extension is current be placed on short, hard-wired lead is partly gone up and extend.These lead extensions are designed to: the bottom standing part has the admittance end of the pin end that can admit on the lead extension, and the post part can be locked to each other by mechanical locking.
Known solution (prior art) is based upon on the basis of the lead extension that protrudes upward of leading line and standard.The lead extension is hollow, and leading line extends therein and further extend to the line anchor with pawl, and when these pawls were activated, they were anchored into the lead part that these posts are partly locked together.
Summary of the invention
The solution that proposes is a kind of instrument to be used as in the lead extension that protrudes upward use now, namely, between lead separately, move this instrument around (around), according to finish the work and fetch a lead/these leads (at least one weak point with long) then up to the needs on surface, these leads be fixedly placed on the polycrystalline substance, pre-position on the submarine structure.Lead stretches out 3.5 meters usually.As what mention, lead stretches out above polycrystalline substance, will have risk and need be removed fishing net etc.
In order can to calculate around moving to another place from a place by the ROV lead that (two) are independent, on the contrary, use one to be equipped with leading line (this leading line need be fixed to the base portion of lead by pawl mechanism, and at each place, need to discharge from these pawl mechanisms again subsequently) lead do not calculate.
Avoided using the leading line from the surface simultaneously, this leading line no longer needs owing to the ROV of good and easy operating.Except the cost costliness of leading line, leading line especially than the deployment in the deep water be unusual time-consuming.For example, fruit Ah (Goa) field in African seashore coastal waters be 1200 meters dark.
Usually need two leads, one longer than another root.Normally, the funnel-form device on the parts to be fallen need at first enter long post.Then, these parts are directed by the rotation horizontal plane, up to the numbering two of funnel-form device be positioned at shorter lead directly over.Then, these parts are fallen on the extension of this shorter lead, and further that first post is downward.
Use new solution, the gross weight of removable lead can reduce, that is, it now will heavily about 44kg.Normally, ROV can mention about 50-70kg.
According to the present invention, the lead extension of described type of beginning is provided, the difference of this lead extension is: the lead extension is connected to the fixing lead part in seabed loosely via the pin and sleeve tube portion on end separately, on the longitudinal direction of described pin and sleeve tube portion, there are gap or space between the described pin and sleeve tube portion, and be furnished with at least one frictional force in the gap on described pin part or in the gap in described sleeve portion and form device, described at least one frictional force forms device and does not contact or engage with another part, unless described lead extension is subjected to lateral force.
This theory is by applying horizontal force against the lead extension, this extension will tilt, and the sleeve pipe of this extension or sleeve part will clamp (pinch) to pin part, and this clamping is assumed to by using described frictional force formation device to be strengthened substantially.Lateral force more up acts on the lead extension, and the moment arm that works is just more long, and the clamping force that correspondingly realizes is just more big.
On the contrary, the lead extension only can be removed in the mode that (by ROV) mentions this extension substantially straight up.As long as the lead extension tilts, it puts up with clamping.The trend that tilts will always take place in the landing operating process of parts on polycrystalline substance, but it doesn't matter for this.This can make the lead extension still be firmly held in the original place.If do not have inclination in the process that descends, also it doesn't matter for this, so these lead extensions are positioned at the original place by they self gravity.
In first embodiment, the lead extension comprises sleeve portion self; And the fixing lead in seabed partly comprises pin part.
In second embodiment or modification, the fixing lead in seabed partly comprises sleeve portion, and the lead extension comprises pin part.
In the embodiment of practicality, frictional force forms device can have the form of O type circle, and described O type circle internally is arranged in the sleeve portion or externally is arranged into pin part, and is arranged in the groove that provides in the inside/outside portion surface of described part.
Preferably, described O type circle by elastomeric material (such as, rubber composition or similar item) make.If existing pin or cannula tip have been positioned on the seabed and only this lead extension is by a new lead extension branch alternative (that is, revising existing equipment), this solution will be especially suitable so.
In another embodiment, the surface, inside of sleeve portion is divided into to have than the upper face of minor diameter and has larger-diameter a little lower surface, and all is furnished with O type circle on each corresponding surface.This means that the lead extension reduces on diameter a little with respect to sleeve portion, this sleeve portion partly has the diameter that reduces with respect to lead then.This part has in abutting connection with occurring over just a point (spot) locates such geometry.
In another embodiment, at least one fluid passage is arranged as the somewhere of wall between frictional force formation device of passing sleeve portion.
In alternative embodiment, frictional force forms device can have the form of tongue and slot device (tongue andgroove means), and wherein, described tongue can form mechanical engagement with described groove.If carried out the payment for whole leads of equipment before finishing deployment, then this solution may be preferred.
In another alternative embodiment, frictional force forms device can have one deck elastomeric material in the gap that is arranged between pin part and sleeve portion form of (such as, rubber).
In another alternative embodiment, frictional force forms device can have the form of the quoit in the gap that is arranged between pin part and the sleeve portion.Described quoit can have any suitable cross-sectional profiles that can clamp to abutment surface.
Preferably, it is long that the lead extension can be 1 to 3 meter the order of magnitude.
At least one be coated with lubricious material in pin end or the cannula tip is such as polytetrafluoroethylene (PTFE) or similar item.
The space that is present between pin end and the cannula tip will eligibly be about the order of magnitude of 1mm, and this is not construed as limiting.In one embodiment, only as example, the outer dia of pin is about 180mm.As another example, two inner O type circles can be placed in the inside of sleeve pipe or sleeve part at a distance of about 300mm.Ideally, these O type circles contact plug not.
